Abstract: Improved computer interface system using multiple independent hardware and virtual human-computer input devices and related enabling subroutines is disclosed. Multiple independent data input devices allow users to input data independently from multiple independent data input devices to operating system. Input device driver decodes input from multiple independent input devices. Operating system interface software interprets data from input device driver. Operating system software further generates and controls multiple cursors or control points. Input device aware program obtains and interprets input devices event message, and controls input device aware objects.

Abstract: Improved computer interface system using multiple independent graphical data input devices is disclosed. Multiple independent graphical data input devices allow users to input data independently from multiple independent graphical data input devices to operating system. Graphical input device driver decodes input from multiple independent graphical input devices. Operating system interface software interprets data from graphical input device driver. Operating system software further generates and controls multiple cursors or control points. Graphical input device aware program obtains and interprets graphical input devices event message, and controls graphical input device aware objects.

Abstract: A security light has a quartz-halogen lamp, a photocell, a passive infrared sensor for detecting motion external to the security light, and a circuit which causes the quartz-halogen lamp to operate at about 50% of full brightness in the absence of detection of motion at night, to operate at 95% of full brightness for a predetermined time interval in response to detection of motion at night, and to be off while the photocell is detecting daylight. A switch allows the user to select a different mode of operation which is similar except that the lamp is kept off in the absence of detection of motion at night. A user-initiated override mode is also provided, which causes the lamp to continuously operate at 95% of full brightness until the photocell detects daylight or until the user disables the override mode.
